Title Sample tree growth data with locations
Downloaded 11 times
Description This file provides measurements of annual radial growth for randomly distributed adult trees in the Rocky Mountains of the United States. Measurements were derived from increment cores collected in 2012 and 2013. A total of 5 tree species were sampled. Sample trees were distributed across a latitudinal gradient from the southern terminus of the Rockies in New Mexico to the Canadian border in the north. Target tree species include: Abies lasiocarpa (subalpine fir), Picea engelmannii (Engelmann spruce), Pinus contorta (lodgepole pine), Pinus ponderosa (ponderosa pine) and Pseudotsuga menziesii (Douglas-fir). Annual radial increment over a 20 year period was measured in millimeters for each sample tree. File headings include: Sample tree ID: Identification code for the sample or target tree Species: Species of the sample tree Year: The year of growth Site: General location of sample tree Longitude and Latitude: Geographical coordinates of sample (based on North American Datum 1983) Elevation: Elevation above sea level in meters Aspect: Dominant terrain aspect in degrees from north Terrain slope: Average slope of land surface measured in percent Stem diameter: Diameter of tree stem at breast height (1.3 meters above root crown) in year of growth measured in centimeters Age: Age of sample in year of growth Ring width: Measured width of annual radial increment in millimeters Date collected: Month, day, and year the sample was collected

Title Neighbor tree location and size data
Downloaded 5 times
Description This file provides data describing the density and configuration of sample tree neighborhoods for calculation of competition indices. The distance to and diameter at breast height (DBH; 1.3 meters above root crown) of all neighboring trees within a 15 m radius of the sample or target tree were measured. A total of 10 sample trees had empty neighborhoods (no neighbor trees within 15 meters). File headings include: Sample tree ID: Identification code for the sample or target tree Sample tree species: Species of sample tree Neighbor tree species: Species of neighbor tree Neighbor tree DBH: Diameter at breast height of neighbor tree in centimeters Distance to neighbor tree: Distance from sample to neighbor tree in meters
